About This Design

Ulam Spiral Round Clock

If you plot every integer in a spiral and darken the prime numbers, something weird happens. A pattern emerges. There's no known way to predict where prime numbers will occur, but the beautiful spiral patterns they create taunt mathematicians with the possibility that there IS a way. Ulam, the mathematician who discovered this effect, did so while doodling on a napkin during a boring conference talk!

This was more than I expected, I was so happy with the product as I was rushed at ordering it for Christmas time frames and wasn't sure if I really had what I wanted however the product arrived and I was absolutely over the moon happy with it. My photos were not great quality so I was really worried about the outcome however I am absolutely thrilled with the prints
